AAGH. Don't modify limits.h! You will break the compiler.

The size of a UTF-8 (8 bits) char is one byte.

You code has issues - sizeof(something) tells you how much space the compiler allocates for something, not the length of a character of a string. The answer is 1 for a single char.

mblen() gets the length of wide characters in bytes, use on wide characters.

What am I gaining besides more... (3 Replies)
